command line calculator Using awk

I love this. Much easier than my previous favorite (also listed here): echo "expr" | bc

Thanks! I created command "calc" from this that I can use from the command line at any time (faster than echo "equation" | bc) ~/bin/calc #!/bin/bash ARG=("$@") x=$( printf "%s" "${ARG[@]}" ) calc(){ awk "BEGIN{ print $* }" ;} calc $x

But at least it didn’t change its tone and the ending was rather satisfactory. https://https://193.168.195.169.com

Thanks for sharing your ideas. I might also like to convey that video games have been actually evolving. Modern tools and innovations have made it easier to create practical and interactive games. These types of entertainment games were not that sensible when the real concept was first being used. Just like other styles of technological innovation, video games way too have had to grow by means of many ages. This itself is testimony towards the fast growth and development of video games.

I have learned result-oriented things via your website. One other thing I want to say is newer laptop operating systems are inclined to allow far more memory to get used, but they likewise demand more storage simply to operate. If your computer could not handle a lot more memory as well as the newest application requires that ram increase, it usually is the time to buy a new Laptop or computer. Thanks ????? ???????

Going to graduate school was a positive decision for me. I enjoyed the coursework, the presentations, the fellow students, and the professors. And since my company reimbursed 100% of the tuition, the only cost that I had to pay on my own was for books and supplies. Otherwise, I received a free master’s degree. All that I had to invest was my time. Usborne Books Reviews
